Better flow and a little more sound to go with the Corsa. It shouldn't throw any CEL's since they are high flow cats and not just a cat delete. If anything I could have my tuner run open loop on the O2 sensors.

Let me know if you end up going for it. I also have a Corsa catback and wouldn't mind a little more sound, but don't want to pony up for longtubes
